Meaning of the Indication Elements
Control of the charging procedure is indicated
via the charge control LEDs 11 and 12:
Rapid-charging Procedure
The rapid-charging procedure is
indicated by flashing of the
green charge control LED 12.
During the charging procedure, the three green
LEDs light up one after the other and briefly go
out. The battery is fully charged when the three
green LEDs light up continuously. The three
LEDs go out again approx. 5 minutes after the
battery has been fully charged.
Note: The rapid-charging procedure is only pos-
sible when the battery temperature is within the
allowable charging temperature range, see sec-
tion "Technical Data".
Battery Charged
Continuous lighting of the
green charge control LED 12
signals that the battery is fully
charged.
Additionally, a signal tone sounds for approx.
2 seconds, which acoustically indicates that the
battery is fully charged.
Afterwards, the battery can be removed for im-
mediate use.
With no battery inserted, continuous lighting of
the green charge control LED 12 indicates that
the mains plug is plugged into the socket and
that the battery charger is ready for operation.
Battery Temperature below 0 °C and above
45 °C
Continuous lighting of the red
LED 11 indicates that the bat-
tery temperature is not within
the rapid-charging temperature
range of 0 °C – 45 °C. As soon as the allowable
temperature range is reached, the battery charg-
er automatically switches to rapid charging.
When the battery is not within the allowable
temperature range, the red battery LED lights
up when inserting the battery into the battery
charger.
Bosch Power Tools
No charging procedure possible
If a different malfunction of the
charging procedure is present,
this will be indicated through
flashing of the red charge con-
trol LED 11.
The charging procedure can not be started and
the battery cannot be charged (see "Trouble-
shooting").
Charging Advice
With continuous or several repetitive charging
cycles without interruption, the charger can
warm up. This is not meaningful and does not in-
dicate a technical defect of the battery charger.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Battery Cooling (Active Air Cooling)
The fan control integrated in the battery charger
controls the temperature of the inserted bat-
tery. When the battery temperature is above
30 °C, a fan cools down the battery to the opti-
mal charging temperature. The switched-on fan
produces a fan noise.
The battery temperature is within the optimal
charging temperature range when the fan is not
running, or the fan may possibly be defective. In
this case, the charging time of the battery ex-
tends.
Operation

Initial Operation

Inserting the Battery (see figure A)
Insert the charged battery 8 from the rear into
the handle of the garden product. Push the bat-
tery completely into the handle until the red
stripe can no longer be seen and the battery is
securely locked.
Note: The garden product will not operate un-
less both locking levels are engaged.
